T0 all whom it may concern.: e .j y i VBe it knownr that l, JOHN R.bNooit, a subject of the King of Great Britain, residing at Brooklyn, inthe county'oflKings and State of New York, have invented certain new anduseful Improvements in Ship Steering andy Propel'ling Mechanism,V ofwhich 'theffollowing is a specification.

This invention' appertainsfto ship propelling yrand steering mechanismsland the, primary object of the invention isr to'pro-i,

vide a, novel mechanism forb'oth steering and driving a vessel7 themechanism being so constructed as to eliminate vibration.

Another object of' the invention isv the provision offnovel verticalfdriving vvlanes t mounted for oscillating n'ioveiiient i-nja horizontalpla-ne', with iio'vel vmea-ns for op'ergit;

ing the driving varies synchronously and' in yopposite directions fordiivingthe ship' and to reduce Vibration`tofamininiuiiivA further:object of the invention is to fprovide novel means for operating saiddriving vii-nes so as to bring about the ex-V 1 elevation'l of thepeditious and effective Working thereof.

A further obgect ofthe invention is `to of the vessel. i -v y i YvArfurrtlier;v Object of the invention 'is yto provide novel vmeans forconstructing :the driving vanes, in order to' insure a lcertainflexibility 'thereto so -a'sto bringabolut the effective opferationroit"the-ship vWithma minimum lamount of vibration.

i @A still further' object. of4 the'inventii-ri is topi'ovide a novelcombined means for propelling and steering a ,vessely i'vhich yWill beVdurable and efficient in use, Onethat Willi be simple and easy tovmanufacture and one which can be incorporated with a conventional vesselat a small-cost.
